The purpose of this paper is to design a robust controller for the new design of hydrazine micro pumps, by studying the real prototype using a high-performance oscilloscope attached to the real pump system. In other words we have designed a relatively accurate mathematical model of the micro pump by using the data extracted with the oscilloscope and then we have calculated and tested a robust controller using backstepping technique. Simulation results are satisfactory regarding the desired criteria. The micro pump consists of an electromagnetic actuator which moves a piston forward and backward (stroke 0 to a few mm). The main advantage in using these new devices consists on increase the capacity maneuverability of the satellite with the same tank volume gain with respect to the existing satellites systems allowing the overall system to operate even if the gas reservoir pressure level is low, thus bringing great advantages (reduced costs, better maneuverability). |
